Numbers 3.6.1 not opening some .xls files
Hi,
Are some .xls files different from others?
I use an external booking system where I can download data.
If the file is .xls it will not open - just shows nonsense. Their .csv files are fine.
I understood the 3.6.1 version had addressed this problem.
I can convert the files but it would be easier just to have them open in Numbers
